Products can be customised The harvesting energy current transformer can be directly mounted in the outdoor exposed, widely used in current measurement, and can generate electrical energy through the wire current induction.

Products can be customised Designed with advanced technology and engineering expertise, our harvesting energy CT products ensure accurate monitoring and extraction of current.

Products can be customised The split harvesting energy current transformer is easy to install and replace, and can provide power to other components.

Split core current transformers are a series of miniaturized openable products designed based on the improvement of current instrument and equipment software processing capabilities. Due to the increase in current monitoring equipment, there is a need for an open-type current transformer that is easy to install and compact.   

Split Current Transformers 5 to 600 amps of alternating current through the center conductor. The split core design allows for non-contact current measurement via magnetic field induction without the need to take the main wire offline and disconnect when installing the CT. This approach enables safer, simpler and portable current measurements.

Products can be customised Clamp-on current transformers with Permalloy cores for high-precision measurements are stable and reliable for long-term operation.

Products can be customised The harvesting energy current transformers can be installed outdoors directly exposed, measuring the current and converting the conductor current into electrical energy through electromagnetic induction, providing energy for other components.

Products can be customised Our current transformers measure and extract electrical energy to power accessories such as sensors.

Products can be customised The harvesting energy current transformers are suitable for use in buried cables and utilise the principle of electromagnetic induction, whereby the magnetic field generated by the current in the conductor is induced through the toroidal coil to produce electrical energy.

Products can be customised Open-close installation current transformer suitable for power collection and power detection.

Permalloy shielding covers are produced from high permeability nickel iron alloy (or Mu-metal) and provide excellent low frequency magnetic field attenuation with low coercive forces.

Hemei Electronics has perfect magnetic shielding technology, our magnetic shielding box has both electric and magnetic shielding for radiated electromagnetic fields.

Electromagnetic shielding is the principle of metal isolation to control electromagnetic interference, from one area to another area of induction and radiation propagation method.

Qualcomm/STMicroelectronics/Huawei HiSilicon/Wuqi Technology, etc. the solutions designed specifically for these companies are widely used. Power line broadband carrier signal coupling isolation technology solution partner.

Coupling transformer, that is, the radio line is often used as a coupling transformer between the poles. For example, the center periphery, input transformer and output transformer of a radio belong to this category. The role of coupling transformer is multi-faceted, it can also be used to achieve impedance matching.

Our current sensors are split-core current transformers characterized by high accuracy and low phase shift.  They are precisely designed for the electronic measurement of AC waveform current, ensuring galvanic separation between the primary circuit (power) and the secondary circuit (measurement). Covering a range from 0 A to 125 A, these current transformers are primarily intended for mounting on the primary circuit.

The split core current transformer is designed based on the principle of quick and easy use. The split structure design of the transformer does not need to disconnect the tested cable or busbar. It can perform safe and simple current testing.

The open-type current transformer is easy to install. There is no need to remove the primary busbar. It can also be operated with power without affecting the customer's normal power consumption. It can be used in conjunction with relay protection, measurement and metering devices.

Permalloy refers to an iron-nickel alloy with a wide range of nickel content, ranging from 35% to 90%. The biggest feature of Permalloy is its high magnetic permeability in weak magnetic fields. Their saturation magnetic induction intensity is generally between 0.6-1.0T.
